MAGHI INE FOR PRINTING IN COLORS.

Specification of Letters Patent No. 8,475, dated October 28, 1851.

To all whom it may concern Be it known that I, RICHARD S. \VEAVER, ofMaysville, in the county of Mason and State of Kentucky, have inventedcertain new and useful Improvements in the Inking Apparatus ofPrinting-Presses; and I do hereby declare the following to be a full,clear, and exact description of the same, ref erence being had to theaccompanying drawings, making a part thereof, in which- Figure, 1,represents a perspective view of the entire apparatus; and Fig. 2, aportion of the ink trough.

Similar letters in both the figures repre sent the same parts.

In the use of different colored ink, for printing bills, cards, &c.,great inconvenience has existed, and much time consumed, for the want ofsome expeditious manner of inking the form. This heretofore, has beendone by hand, or by a series of rollers, each one of which has to beseparately furnished with its peculiarly colored ink, thus making theprocess tedious, and consequently expens1ve.

The nature of my invention consists, in the construction of anadjustable ink trough, which can be divided into any number of cells forcontaining the ink, and perforated in such manner, as to allow the inkto flow onto the receiving roller, in just such regulated quantities, aswill cover the particular line of type in the form, for which any givencolor may be selected. Also, in using for a distributing roller, ametallic cylinder, which receives the ink from the receiving roller inlines or belts, and transmits it to the inking roller, in preciselysimilar lines or belts, and from which inking roller, the form issupplied with ink, laid on as it is received from the cylinder.

To enable others skilled in the art to make and use my invention, I willproceed to describe the same with reference to the drawln 's.

011 the top cross pieces of an iron stand or frame A, strengthened bythe cross braces B, is arranged a zinc, brass or other metallic cylinderC, being supported in its journals in suitable open boxes on said crosspieces, so as to be easily removed for being cleansed; and to one ofwhich journals, outside of the frame is attached the crank D, which maybe turned by hand or otherwise, for placing the ink properly on thecylinder C, and which cylinder also, by means of friction gives a rotarymotion to the receiving roller E, and inking roller F, by which saidcylinder receives the ink from the roller E, and imparts it to theinking roller F. The cylinder C, is made of metal for two purposes viz:to prevent the lines or belts of different colored ink, which itreceives, from running or blending with each other, and preventing theabsorption of the oily matter in the ink, which any porous materialwould do; also, the facility with which it can be cleansed whenrequired, for a different combination of colors. The cylinder might becovered with other mineral substances either vitrified or otherwise, butI mention the metals, as being the most common and yet the cheapest.

The receiving roller E, and inking roller F, may be made in the usualmanner of making similar rollers, and may be covered with a compositionof glue and molasses, or other well known elastic materials, which arenonabsorbents, so that each may perform its necessary function, viz: theroller E, by its elasticity to fit closely against the perforated sidea, (Fig. 2) of the trough G, on the outside thereof, so as to check theflow of ink through the perforations in said trough, merely receivingsuch quantity of ink'in the small recesses or holes which form in thesurface of said roller, or which may be formed therein, and whenrequired, transmitting said ink to the cylinder C, upon which it isreceived in lines or belts, the cylinder C, in turn transmitting it tothe inking roller F, in precisely the same form. The inking roller iscovered with the elastic material for the purpose of more thoroughlyinking the form, while it at the same time, protects the type from beingbruised or battered.

By placing the ink trough over the form, and adjusting the partitionstherein, so as to correspond to the lines of type in the form, and thenreplacing said trough on the stand prepared for it, and filling thecells therein, with such colored ink as may be desirable, the samefacility for inking a form with various colors is obtained, as could bewhen one color alone is used.

On suitable bearings cast on top of the stand or frame, on the rearthereof, is placed the ink trough G, which may be made of.

wood, metal, or parts of each, said trough having 1ts sides groovedperpendicularly, for the purpose of recelving the partitlons c,

which fit closely therein, and which may be, if found necessary, furthersecured in place by a bar running across the tops thereof fro-m end toend of the trough, and held in any well known manner. The side of thetrough next the receiving roller E, is inclined or sloping underneath,for the purpose of allowing said roller to move up to and against saidinclined side (as shown by red lines in Fig. 1,) for the purpose ofreceiving its supply of ink through the small perforations in saidinclined side (as represented at a, Fig. 2.) The trough G, is securedto, and made adjustable on its bearings by the set screws (Z, which passthrough slotted holes in the lugs e, which are arranged on the bottom ofsaid trough, so that the pressure of the receiving roller E, against theperforated side of the ink trough G, may be adjustable at pleasure, butshould, at all times, be suficient to hold it there by the friction, soas to prevent the ink from passing through said perforations. If it isdesired to have for the roller E, a greater surface on the perforatedplate a to rest upon and receive ink from, than it would have by makingsaid plate straight, it may be made concave, so as to reach fart-heraround on the roller.

The receiving roller E, is hung by its journals upon one set of the armsof V- shaped pieces H, at each of its ends, which have their bearings inthe frame, as seen at f; the axis of the roller E, is eccentric withregard to the axis of the cylinder C, so that when said roller E, is inthe position as shown by the dark lines, it will be in contact with thecylinder C, so as to be rotated by it, and impart to it the ink which ithas received from the trough while resting against it, in the posit-ionas shown by the red lines, and in which said position it does not touchthe cylinder C. To the other set of arms of said V-shaped pieces, issecured a rod I, which connects them together, and in the center ofwhich rod is placed a lever J, projecting rearward, which raises 0rlowers said arms, and the roller E in them, up to receive, or down toimpart, ink to the cylinder as may be required. The journals of theroller E, extend through, and a short distance outside of the arms ofthe V-shaped pieces, so thatwhen said roller is giving off ink to thecylinder, as represented by the dark lines, the points of said journals,will rest against, and rotate in, rounded recesses in the frame (as seenat z',) which prevents it from being forced away from the cylinder C, asit would otherwise be, if merely sup ported by the V-shaped piece alone.

The inking roller F, is provided with flanges K, at its ends, which fitoutside of the cylinder C, and its journals rest and rotate in the barL, which extends lengthwise across the top of said roller, having itsends bent down to receive said journals, and in the center of said baris a lever or arm M, which extends back to, and rests in a slot in anupright support N, rising from the base of the frame. The sides of thelever or arm M, at its end are notched out, so that when it rests insaid support N, it will be held firmly in position, to be rotated by thecylinder G, upon which it rests, when in this position, and from whichit receives the ink in lines or belts to be transferred to the form asbefore described. The arms 0, of the frame, on their inner sides areprovided with ways, slightly grooved out, upon which ways and in saidgrooves, the flanges K, of the roller F, run, and is guided, whilepassing to and over the form for the purpose of inking it. Whensuflicient ink is on the roller F, the lever M is raised out of thesupport N, and the roller is run forward, being guided by the ways abovementioned, and inks the form with the various colors as arranged in thecells of the ink trough, thus inking the whole form with thediiferentcolors of ink, by one and the same roller, and at one and the sameoperation.

Having thus fully described my invention, what I claim therein as new,and desire to secure by Letters Patent is In combination with receiving,distributing and inking rollers arranged as herein described, theadjust-able ink trough, provided with removable partitions, andperforated side, so as to give out the ink in lines or belts,corresponding with the lines or size of the type in the form, for thepurpose herein described.
